UNITED STATES PATENT OFFICE.-

DAVID LIPPY, OF MANSFIELD, OHIO, ASSIGNOR OF THREE-FOURTIIS TO LORENZO D. PATTEN, CHRISTIAN K. HERSHEY, AND JAMES T. SAW-' HILL, OF MANSFIELD, OHIO.

SEPARATOR-SIEVE;

SPECIFICATION forming part of Letters Patent No. 692,682, dated February 4, 190a. I Application filed December 6, I900. Serial No. 38,946. (No model.)

To aZZ whom it may concern;

Be it known that I, DAVID LIPPY, a citizen of the United States,residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Separator Sieves; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the figu res of reference marked thereon, in which Figure l is a perspective view. Fig. 2 is a bottom or under side View showing a portion of the sieve and the mechanism for adjustment. Fig. 3 is a longitudinal section showing a portion of the sieve.

The present invention has relation to separator-sieves; and it consists in the different parts and-combination of parts hereinafter described, and particularly pointed out in the claim.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

In the accompanying drawings, 1 represents the end members of the frame, and 2 the side members thereof, said members be ing connected together in any convenient and well-known manner, so as to constitute a rec--- tangnlar frame.

To the side members 2 are connected the fixed bars or plates 3 in any convenient and well-known manner, which fixed bars or plates are spaced from each other, as illustrated in the drawings, and near the rear edges of the fixed plates 3 are hinged the front edges of the adjustable blades 4:, said adjustable blades being located between the plates 3, as illustrated in the drawings.

For the purpose of providing a means for holding the blades 4. in proper relative position with reference to thefixed plates 3 the rods or bars 5 are provided, which rods or bars are pivotally attached to the side members 2.

For the purpose of strengthening the frame proper and supporting the plates 3 the center rail 6 is provided and is attached to the end members 1 in any convenient and wellknown manner.

The hinged blades 4 upon one side of the center rail 5 are provided with the down turned flanges or arms 7, which may be formed integral with the blades, or they may be formed separate and attached in any convenient and well-known manner.

It will be understood that the adjustableblades or slats 4 should be formed of such a size that when they are brought into a close position, or, in other words, substantially the same plane as that of the fixed bars 3, they will close the space between said fixed bars or plates.

It will be understood that the space or opening between the fixed bars or plates 3 can be varied by adjusting the hinged blades or slats up or down, and for the purpose of providing a means for so adjusting the hinged blades 4 the rod 8 is provided, and its front or forward end is provided with the downturned flange 9, so as to form a handle to operate the. rod 8. The rod 8 is extended rearward and its rear end pivotally connected to one of the downturned flanges 7, and for the purpose of cansing all of the blades 4 to move in unison the connecting bar or rod 10 is provided, to which rod or bar are pivotally connected all of the v downturned flanges 7. For the purpose of holding the blades 4 at any desired point of adjustment the rod 8 is provided with the notches 11, which notches engage the cut-out end of the plate 12, said plate being connected in any convenient and well-known manner to the front end rail.

For the purpose of normally holding the V lever 8, together with the adjustable blades 4,

in fixed adjustment and preventing any accidental displacement of the adjustable parts the spring 13 is provided, which spring is so located and formed that it will press or bear against the outer edge of the bar 8.

When it is desired to change the adjustment of the hinged blades 4:, the outer end of the bar 8 is moved laterally, so as to disengage the notches 11, after which said bar is free to be moved back and forth to any desired point of adjustment Within the limits of its movements.

For the purpose of strengthening the blades 4 and at the same time providing for better adjustment of the open space between said hinged blades or slats and the fixed bars or plates said hinged blades or slats are each provided with the downtnrned flanges 14:.

Having fully described my invention, What I claim as new, and desire to seen re by Letters Patent, is-

In a separator-sieve of the class described, the combination of a rectangular frame provided with transverse fixed strips or plates spaced from each other, transverse rods or bars journaled to the frame, and located between the fixed strips, blades or slats fixed to the said journaled bars said blades or slats provided with downtnrned edges, downof two Witnesses.
